XZ, X.Z., or xz may refer to: xz, a lossless data compression file format based on the LZMA algorithm, often with the file extension '.xz' XZ Utils, a set of free lossless data compressors, including the command xz Yamaha XZ 550, a motorcycle produced c. Xz is a general-purpose data compression tool with command line syntax similar to gzip and bzip2.The native file format is the.xz format, but the legacy.lzma format used by LZMA Utils and raw compressed streams with no container format headers are also supported.

This Go language package supports the reading and writing of xz compressed streams. It includes also a gxz command for compressing and decompressing data.

xz是一个使用LZMA/LZMA2压缩算法的无损数据压缩文件格式。
设计[编辑]
和gzip与bzip2一样,同样支持多文件压缩,但是约定不能将多于一个的目标文件压缩进同一个归档文件。相反,xz通常作为一种归档文件自身的压缩格式,例如使用tar或cpioUnix程序创建的归档。xz在GNUcoreutils(版本7.1或更新)[1]中被使用。xz作为压缩软件被收录在Fedora(自Fedora 12起)[2]、Arch Linux[3]、FreeBSD、Slackware Linux和Funtoo Linux中。
实现[编辑]
一个xz文件格式的实现XZ实用程序已可在网上自由获得,在GNU LGPL和GNU GPL条款下发布,同时还有大量软件进入了公有领域(例如liblzma等)。[4]GNUtar自版本1.22起使用这一软件透明支持xz文件格式(就如同其处理gzip格式或者bzip2格式一样)。[5][6]
xz命令行程序曾有过一个名为pxz的分支,提供多线程压缩功能,后来xz在5.2时本身就直接提供多线程了。
7-Zip在9.04 beta版支持了xz文件格式。[7]
WinRAR 在版本 5 支持了xz格式。
使用[编辑]
xz以其优异的性能和压缩比[8]成为了不少开源软件(例如GNUcoreutils项目、[9]Debian系列系统deb包格式、openSUSE、[10]Fedora[11] 、Arch Linux、[12]Slackware、[13]FreeBSD、[14]Gentoo、[15]GNOME[16]以及TeX Live[17])的压缩方式之一,同时也可以是压缩Linux 内核的格式。[18] 2013年3月,kernel.org宣布使用xz作为发行内核源代码的默认格式。[19]
